Dealing with dynamics of processes that repeat themselves regularly,
this revised and updated edition extends the thread from 1980 to the
present day, concentrating on areas of interest where there will be much
activity in the future. This involves going through spatial biochemical,
electrophysiological, and organismic dynamical systems and patterns that
were discovered by pursuing the theme of phase singularities introduced
in the original book. In particular the work on excitability in cell
membranes will be thoroughly updated as will the references throughout
the book.
